IC204, Micropower Supply Voltage Supervisor (CM3403)
Pin Description:
Pin Description:
PIN(S) NAME DESCRIPTION
1 GND Negative reference for all signals.
2 RESET
Active low reset output. When the sence threshold has been exceeded, the RESET signal will remain
active for an additional 140(min.) after which it is taken inactive. During a "brownout" condition, RESET
will immediately be taken active. Internal circuitry ensures RESET
will remain active even when the sup-
ply voltage is as low as 0V.
3V
CC
Supply input signal which is monitored by the sense comparator. This input is compared to the 2.93V
(CM3403-29ST) or 4.63 (CM3403-46ST) reference to determine the state of the output.
